<h1>Welcome to Visualizations of Earthquakes and Volcanoes</h1>
<img=src "./etnastromboli.png>
      <img=src "./stromboli.png">
<p> Raluca Nicola created a visualization for <a href="https://ralucanicola.github.io/earthquakes-viz/">earthquakes</a> which creates a 3 dimensional map of earthquakes on Earth's globe. The visualizations can be adapted to visualize sections of the Earth using any .csv file from the USGS database.</p>
<div id="details">
      <div id="legend">
        Earthquakes are marked by yellow or green spheres, volcanoes are marked by red spheres at the surface. In this visualization, small yellow
        spheres
        are earthquakes with magnitudes between 2.5 and 7 depending on the visualization and the number of earthquakes. Larger red spheres are earthquakes greater than 7 magnitude or
     are the volcanoes on the surface. Depending on the individual visualization, the color and size of spheres are interpolated.
        Earthquake depth is exaggerated by a factor of 6. The orange lines represent the boundaries of the tectonic plates. Earthquake data from
        <a href="https://earthquake.usgs.gov/earthquakes/search/">USGS</a>.
